- 6 out of 20 people in a business have a language certificate. Accordingly, how many of 10 randomly selected people should have a language certificate?10. For adults, certain type of cancers can be treated with multiple health interventions. To gain information about all Maryland-based treatment centers a survey is sent to a randomly chosen group of 25 Maryland based treatment centers that asks about the recommended interventions for cancer patients based on medical records, insurance, and income. All of the randomly selected treatment centers completed the survey. The sample is: For adults, certain type of cancers can be treated with multiple health interventions.

- Of 1,050 randomly selected adults, 360 identified themselves as manual laborers, 280 identified themselves as non-manual wage earners, 250 identified themselves as midlevel managers, and 160 identified themselves as executives. In the survey, 82% of manual laborers preferred trucks, 62% of non-manual wage earners preferred trucks, 54% of mid-level managers preferred trucks, and 26% of executives preferred trucks. Which distribution should you use for this problem?A lawyer received a complaint from a representative for factory workers somewhere in Pampanga. The workers were being forced to work for more than 8 hours. 8 hours is the average/normal work time per day in the Philippines as stated in the Labor Code and was initially stipulated by their employer when they were hired. They also reported that they were not receiving any compensation for their overtime work. The lawyer commissioned you to conduct a survey involving 10 randomly selected workers from the factory to inquire about their work time. The data you collected is displayed below. 8 hours 6 hours 5 hours 10 hours 14 hours 3 hours 9 hours 8 hours 11 hours 14 hours Use the P-Value Approach in testing the complaint of the workers. 1) Estimate μ at 99% confidence interval. 2) If you drew the wrong conclusion and gave the labor lawyer the wrong advice, what type of error would you have committed?A. The Computer Geek Org has 23 members: 3 freshmen, 5 sophomore, 7 junior, and 8 senior students. If you are going to pick a certain number of name/s at random, at least how many should you pick to make sure that you have 2 students with the same year level? Use the pigeonhole principle and state your conclusion.
- The Higher Education Research Institute at UCLA collected data from 203,967 incoming first-time, full-time freshmen from 270 four-year colleges and universities in the U.S. 69.5% of those students replied that, yes, they believe that same-sex couples should have the right to legal marital status. Suppose that you randomly pick eight first-time, full-time freshmen from the survey. You are interested in the number that believes that same sex-couples should have the right to legal marital status. Let the random variable X= the number that reply "yes", X∼B(8,0.695).

Would they be interested in purchasing items from the supermarket/pharmacy online or through a mobile application? Would they be willing to pay a subscription fee to utilize this service? If yes what is the maximum fee that they would be willing to pay. The amount of money they are willing to pay to have the goods delivered to them. In the absence of a subscription fee or delivery fee, would they be willing to pay a marginally higher price for the good purchased online?

In 30 cases randomly assigned, the investigator asked 'May I use the machine ?'(let's call this group the 'request-only' group). In that case, 18 out of 30 people allowed the investigator to go first. In the other group of 30 people, the investigator asked 'May I use the machine because I have to make copies?' (let's call it the 'bad reason' group). In that case, 28 out of 30 people allowed the investigator to go first. You can enter the data yourself, or you may enter the data (called `d`) by copying and pasting the code below (in blue). Note that several questions will be associated to these data. #-------------------------------------------------------------- # Code to enter data 'd' d = rbind(c(28,2), c(18,12)); colnames(d) = c('Yes', 'No'); rownames(d) = c('Bad reason','Request only'); d = t(d); d #-------------------------------------------------------------- The data should look like that:…
